Scientists detect molecular water and cold ‘water traps’ on the Moon
... of Hawaiʻi, were able to clarify a water signature in the form of H2O at 6µm. This spectral signature at 6 μm is not shared by other hydroxyl compounds say the team, so its identification is without doubt that of H2O and based on the strength of the...

OSIRIS-REx discovers ingredients for water on Bennu
... Infrared Spectrometer (OVIRS) and the OSIRIS-REx Thermal Emission Spectrometer (OTES), have revealed the presence of hydroxyls; a type of molecule made up from an oxygen atom bonded to a hydrogen atom that together form OH. Although not quite...

PROSPECTing for lunar polar volatiles
...-24 mission was reported to contain traces of water. More recently multiple orbiter instruments have detected elevated levels of hydroxyl (OH) or water on the lunar surface layers at mid-latitudes. Perhaps the most exciting discoveries, however, have...
